Claims.

The object of my invention is to provide an improved clip for fastening shingles together to complete a roof, to provide a clip of improved shape for this purpose and of a material that 5 will not rust. I attain these and other objects of my invention by the device illustrated in the acompanying drawing, in which- Figures 1 and 2 are plan views of different arrangements of shingles or roofing to which the clip has been applied;

Fig. 3 isa perspective view of the clips applied to the shingles;

Fig. 4 is an edge elevation of one of the clips;

Fig. 5 is a top plan view of one of the clips; and

Fig. 6 is an end view of the clip viewed from the open end.

Like characters of reference designate like parts in each of the several views.

Referring to the accompanying drawing, I provide a copper clip I consisting of a relatively long lower leg 2 terminating in a pointed end 3, shoulder 4, slanting upper leg 5 and bent end 6 having the engaging point I. The clip may be applied to shingles or roofing laid by various methods such as illustratedln Figs. 1, 2 and 3, by the strips of roofing S and S.

In use the lower leg 2 is inserted between the top edge of the second underlaying single section and the bottom edge of the first underlaying shingle section. The shoulder enfolds the lowers edges of overlaying and underlaying shingles. The upper leg 5 rests on top of and over the overlaying shingle with the point 1 in position to engage the overlaying shingle when set in place with a slight hammer blow. One clip is used for each shingle. They may be used as the shingler proceeds, or the entire roof may be applied and then the clips applied. The point I is for engagement of the overlaying shingle, its purpose being to hold the clip in place. It does not enter the underlaying shingle. For this reason there is a freedom of movement between shingles which allows expansion and contraction, thereby preventing buckling. .This is an important feature of the invention. The clips preferably are made of copper soft enough to bend easily yet strong enough to securely interlock shingle sections in their relative positions. While I may make a cheaper clip of galvanized iron, the copper clip has inherent advantages over the galvanized iron clip in being non-rusting.

The device is easy to handle and does not requirespecial tools for its use. It is not easily this has nothing whatever to do with the holdnoticeable on the roof and does not detract in any way from the appearance of the roof.

This clip can be used in any position where two layers of material come together at the edges. It' need not meet a hole at any given 5 place; it makes its own hole where needed.

My clip can be used in any position where there is a side overlap or where one section overlays another, the lower edges meeting. The overlap may be of any desired width. The clip always enfolds two sections of material. The clip point does not pierce the overlaying section all the way through, its function being merely to hold the clip in place. It does not pierce the underlaying section at all. It does not require the material to be punched or cut to make certain or definite spacing to use it. It permits the material or shingles to be laid from either direction on the roof, in any size or any exposure. As it can be used at any time it can be used for repair work where shingles have not been particularly designed for clip use.

The clips that are now in general use are most all fastened to both sections of material with a driven point or nailed or they must meet certain cut outs or holes in the material. They are so formed that they tangle to the point of making the clipping operation very slow. The cost and the time are considered against the laying operation and where this is excessive the clip loses its value.

My clips are easy to handle and do not have to be strung on a stringer to prevent tangling. They are sturdy but small and do not detract from the appearance of the roof. 35

Roofing manufacturers are held to certain tab length by the Board of Fire Underwriters and can not use the underwriters label where tabs are so long that they blow up. With this clip and on account of its freedom of movement they can if they so choose increase the length of the tab as when fastened with my clips the tabs will neither buckle nor blow up. I

The clip is adapted to interlock any type of material, whether designed for its use or not, and always permits of a free movement.

Observe that the point on applicant's clips is only there for the purpose of preventing the clip from falling out of its position, and aside from ing of shingles or roof materials in position as the already driven nail in regular roofing application takes care of securing the shingle or roofing material to the roof deck. The idea of applicant's clips on any type of roof is simply to lock two sections of materials together so as not hold the shingle to the roof. As far as the hold power of applicant's clips is concerned, it does not make any difierence as to the relative length of either the upper or lower legs.

What I claim is:

l. A clip of the type described comprising a relatively long lower leg, an upstanding shoulder of a height equal to the thickness of at least, two shingles, an upwardly slanting upper leg, and a downturned pointed end substantially straight so it can be driven into the shingles, and in which said upper leg terminates and which is only of sufiicient length to engage the outer shingle only.

2. A clip for fastening overlaying shingles on a roof and made of a single strip of non-rusting metal of suflicient flexibility to bend easily, said strip comprising a pointed lower leg, an upstanding shoulder of a height equal to the thickness of at least two shingles, an upper leg bent in an upwardly slanting direction, said upper leg terminating in a downturned piercing and bevelled end substantially straight so it can be driven into the shingle, and adapted to enter only the outer shingle when said upper leg is struck by a hammer.

3. A clip for fastening overlaying shingles on a roof and made of a single strip of copper of suflicient flexibility to bend easily, said strip comprising a pointed lower leg, an upstanding shoulder of a height equal to the thickness of at least two shingles, an upper leg bent in an upwardly slanting direction, said upper leg terminating in a downturned pointed end substantially straight so it can be driven into the shingle, and of only suflicient length to be driven into but not through the outer shingle.

4. A clip for fastening overlaying shingles on a roof, said clip being made of a single flat strip of non-rusting metal of suflicient flexibility to bend easily, said strip comprising a relatively long lower leg, an upstanding shoulder of a height equal to the thickness of at least two shingles, an upper leg bent in an upwardly slanting direction, said upper leg terminating in a downturned pointed end substantially straight so it can be driven into the shingles, and of only sufficient length to penetrate part way through the overlaying shingle to hold the clip in place, the upstanding shoulder being of sufficient length to permit the clip to enfold a plurality of overlaying shingles.

5. A clip of the type described comprising a relatively long lower leg, an upstanding shoulder of sufllcient length to permit the clip to enfold two overlapping shingles where their lower edges meet, an upwardly slanting upper leg, and a downturned pointed end substantially straight so it can be driven into the shingles, and in which said upper leg terminates and which is adapted to pierce only part way through the uppermost of the aforesaid shingles.
